External mastic in Hampton Wick: local notes
With historic houses such as Hampton Court Palace (about 1.4 miles south-west) nearby, there’s older building stock in the area around Hampton Wick as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts.
Rented homes near Hampton Wick station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as St John the Baptist Church of England Junior School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. Hampton Wick is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

External mastic in Hampton Wick, done properly
On houses, flats and commercial buildings across Hampton Wick, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you are dealing with failed sealant between panels on a façade and plants rooting in failed movement joints, we can put it right.
Modern London flats rely on sealed movement joints and cladding joints. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Ask before painting over external sealant
- Don’t let climbing plants root in the sealant
- Never let anyone fill a movement joint with mortar
- Act on the first splits you see
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Different surfaces, different methods
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- How easy the joints are to reach
- Whether there’s mould to deal with
- The size of the job
- When we can work, for business premises
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Hampton Wick. It helps if you can point us to a visitor permit or a bay close to the door.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Move anything stored near the joints

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
